Technical Hydraulics

Back to homepage


The Technical Committee on Hydraulic Applications (TC-H) is dedicated to the scientific and engineering development of geosynthetic systems. This committee promotes the dissemination of knowledge, technology, research findings, design and construction methodologies related to hydraulic applications of geosynthetics, such as drainage, erosion control, and coastal protection in geotechnical and geoenvironmental engineering.

Planned Activities of the TC-H:

  • Technical session planning and organization (e.g., within IGS regional and international conferences).
  • Compiling summaries of regulations in various countries.
  • Making recommendations for geosynthetics in specific applications.
  • Organize focused workshop activities to educate and build a technical consensus, address problems and solve scientific needs.
  • Produce a state of practice document for each of the three main application areas (erosion, drainage, coastal). These documents should form the foundation to create a platform for teaching engineers.
  • Include geosynthetic drainage materials for design with HELP (Hydraulic Evaluation of Landfill Performance) model.
  • Check current IGS Leaflets on Drainage, Erosion Control, and Coastal Protection, and translate into other languages.
  • Attracting young members to the committee.
  • Continuously update content to the TC-H section of new IGS website.
  • Work with the IGS Educate the Educators (EtE) initiative program.
  • Liaise with other societies and institutions with similar interests.
